Description

Technical Field

[0001] The utility model relates to the technical field of LED lamp heat dissipation, and in particular to a graphene LED lamp heat sink. Background Art

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured to the bracket with silver glue or white glue, and then connected to the chip and circuit board with silver wire or gold wire. It is sealed with epoxy resin on all sides to protect the internal core wire, and finally the outer shell is installed, so the LED lamp has good earthquake resistance.

[0003] While providing high-brightness lighting, LED lamps also have the disadvantage of generating a lot of heat. The long-term operation of the lamp beads on the LED lamp in a high-temperature environment will affect the service life. In view of this, radiators for dissipating the heat of the lamp beads have appeared on the market. The specific heat dissipation structure is a graphite heat conductive plate arranged on the outside of the LED lamp. The heat conductive plate absorbs heat and transfers the heat to the radiator. The radiator is provided with heat dissipation fins, which exchange heat with the external air to complete the heat dissipation. This heat dissipation structure can effectively prevent the local operating temperature of the LED lamp from rising to a certain extent and extend the service life. However, in a room with poor air flow, after the heat dissipation of the heat fins, the high-temperature gas will gather directly above the LED lamp for a long time, resulting in a poor heat exchange rate, and will burn the objects above the LED lamp and cause damage to the objects. Utility Model Content

The heat dissipation efficiency of the graphene LED lamp can be improved, the discharged high-temperature gas can be quickly diffused to the surroundings, the hot air can be avoided from gathering, and the damage to the upper structure can be reduced, and the structure is simple and compact.

[0006] According to the graphene LED lamp heat sink, a thermally conductive silicone sheet is attached to the upper end of the LED lamp panel, and the thermally conductive silicone sheet is located between the heat sink and the LED lamp panel, which can ensure the heat dissipation effect of the LED lamp and play a buffering effect to prevent the LED lamp from being damaged when it is hit.

[0007] According to the graphene LED lamp heat sink, the upper end of the heat sink is fixedly connected to a lower support column, the top of the inner wall of the shell is fixedly connected to an upper support column, and the upper end of the lower support column is connected to the lower end of the upper support column, and the middle of the lower support column and the upper support column are respectively provided with screw holes, and the screw holes penetrate the shell, and screws are threadedly connected in the screw holes. It is convenient to disassemble and clean the LED lamp to ensure the heat dissipation effect.

[0008] According to the graphene LED lamp heat sink, the inner wall of the lampshade is fixedly connected to the LED lamp panel and the heat sink by glue, which is used to pot the LED lamp to prevent external impurities from contacting the interior of the LED lamp.

[0009] According to the graphene LED lamp heat sink, there is a gap between the heat dissipation fins and the connecting column, and the adjacent ends of a plurality of heat dissipation fins are staggered, so that the hot air is counteracted when discharged, and thus rotates and rises to be discharged from the LED lamp, thereby increasing the air flow rate.

[0010] According to the graphene LED lamp heat sink, the heat dissipation fins are made of aluminum alloy, which ensures the heat conduction efficiency of the heat dissipation fins and reduces their weight.

[0011] The beneficial effects of the utility model are as follows: the heat generated by the LED lamp panel is conducted through the heat dissipation plate, and the contact area with the air is increased through the heat dissipation fins. The hot air after absorbing the heat is discharged from the heat dissipation holes based on the principle of hot air rising, and the air at normal temperature enters the shell through the air inlet, thereby dissipating the heat of the LED lamp. During the rising process of the hot air, it contacts the auxiliary heat dissipation columns, and the hot air diffuses to the surroundings through the inclined surface of the auxiliary heat dissipation columns, thereby avoiding the accumulation of hot air and reducing the damage to the upper structure.
